Writing this field releases a lock and allows for the
generation of release events to the IPC interrupt
structures, but only when the lock is acquired
(LOCK_STATUS.ACQUIRED is '1'). The IPC release
cause fields associated with this IPC structure are set
to '1', but only for those IPC interrupt structures for
which the corresponding bit field in INTR_RELEASE[]
is set to '1'.
SW writes a '1' to the bit fields to generate a release
event. Due to the transient nature of this event, SW
always reads a '0' from this field.
